The roll out of a new mental health crisis line for the entire U.S., is scheduled to happen on July 16 — the blink of an eye in bureaucratic time. People in mental health crises or their family members will soon be able to dial 988, instead of 911 or the harder-to-remember 800-273-8255, the number for the National Suicide Prevention Lifeline.
